You are currently viewing Solenoid Maintenance: 7 Signs It’s Time for a Replacement

You can’t get too far into the summer without hearing about someone’s golf cart breaking down on the course. It’s a common problem, and it usually happens because of a straightforward issue: solenoid maintenance. If you’re using your golf cart regularly, you should perform routine checks to ensure that everything is working correctly and replacing parts as needed. This article will help you identify 7 signs that indicate it may be time for a replacement!

Seven symptoms of the lousy solenoid on a Golf cart

Noise when accelerating:

If you notice noise when starting your golf cart, that might be an indication of the solenoid. A worn-out or dirty solenoid can cause this issue, and it may need to be replaced for proper functionality. The solenoid can also cause noise while you’re accelerating, like a whining sound.

Another way the solenoid might not work correctly is if it doesn’t seem to engage during acceleration or disengage during braking. This means the solenoid is probably in need of a new part; get it replaced as soon as possible!

Noise when stopping:

If you hear rattling or clunking while your golf cart comes to a stop, this might be an indication that the solenoid needs replacing as well. The solenoid should disengage when you break to allow the chair to slow down, and if it doesn’t, then this is a sign that it needs to work.

The solenoid also might not be working correctly if your accelerator pedal feels stiff or sticks intermittently. This means the solenoid isn’t fully engaging with every press of the pedal and might need replacement.

If you hear a continuous humming sound from your golf cart when it’s running or accelerating, this is another sign that the solenoid needs replacing. It should only make a noise briefly as it engages with each push of the accelerator pedal, so if there’s any other noise coming from underneath your seat, this might be a sign of an issue.

This is another sign that the solenoid might need replacing. Suppose you’re getting a lot of resistance on your accelerator pedal. In that case, this could be down to an improperly working solenoid. It may have lost its oil seal and affect the throttle sensor needle, making adjustments difficult for you at higher speeds or accelerating quickly.

Poor Acceleration:

A bad solenoid can also cause poor acceleration, as it helps to regulate the speed of your vehicle when you’re accelerating quickly. If there is no oil in the solenoid, this could be an issue that needs to be repaired soon so that your car accelerates smoothly and promptly.

If you notice that your vehicle is not accelerating well, it could simply be the solenoid – before going to a mechanic. However, try checking under your car for any signs of oil, and if these are present, make sure you take care of this issue as soon as possible so that there’s no more trouble with acceleration.


Solenoid Poor Acceleration

Reduced Gassing:

One thing that is very notable about any car or golf cart with a bad solenoid is that it will not gas up as well – this could indicate a problem with the oil pump or even cause by the lack of fuel. Still, regardless, if you notice any issues with your vehicle gassing, then it’s best to get these sorted out before they become too much trouble.


Reduced Gassing

Poor Range:

A lousy solenoid will not push the fuel to your engine as well, and so it’s likely that you’ll notice a reduction in the range – any number of things could cause this, but if you see problems with your vehicle, then try checking for signs of oil first.

Lower Current:

A bad solenoid can cause issues due to electrical problems that will cause a lower current to the rest of your engine – this could lead to an increase in fuel consumption. So it’s best to get these sorted out if you are noticing any issues with either.

Recently replaced starter, but not starting:

If you recently replaced your golf cart’s starter, and it cranks up but fails to start- that may be a sign of lousy solenoid issues. You can also have this problem if the engine is running rough or stalls out randomly.

Your vehicle is having a lot of trouble starting; it could be due to the solenoid not activating correctly. The best thing to do in this situation would be to look underneath for any noticeable leaks or signs of oil under the vehicle – as if these are present, then there’s likely an issue with either the solenoid’s seal or its oil.


If any of these symptoms sound familiar, contact your local golf cart mechanic to get a diagnosis. Replacing the solenoid can be an easy fix and may save you from buying another starter in the future.

Frequently Asked Questions:

What is a solenoid?

A Golf cart solenoid, or starter motor, activates the ignition of your engine. If you’re having trouble starting your vehicle and it’s due to an issue with the starter motor (solenoid).

How do I know if my solenoid is faulty in my Electric cart?

One of the best things to look for is leaks. If you can see oil or gas leaking from underneath your gas cart, it’s likely that there may be a potential issue with one of these seals: starter seal, flywheel seal, and a clutch pack cover gasket.

Signs that your faulty solenoid may include the vehicle not starting in low to moderate temperatures, high oil consumption (over a quart between changes), and possible grinding noises once the engine startups, weak battery, and less voltage to start can also be some of the symptoms.

What are the signs of a faulty solenoid Gas Golf Cart?

some of the most common symptoms that demand instant repair are:

  • The vehicle won’t start in low to moderate temps.
  • High oil consumption (over a quart between changes)
  • Grinding noises once the engine starts.

What does the solenoid do?

The starter motor is responsible for engaging your engine’s flywheel. The solenoid controls the flow of current to turn on and off during operation, which helps maintain speed when you shift gears. It also shuts down power from the battery once it has been disconnected or drained enough that the vehicle no longer starts.

Suppose your vehicle is exhibiting one or more of these symptoms. In that case, you’ll need to replace the solenoid with a genuine factory part and make sure all components are correctly connected before starting it up again for the first time. This will help ensure that you’re able to start in any temperature condition while also preventing wear on other sensitive parts.

Where is solenoid located?

The solenoid is usually mounted on the starter or near it and has two heavy-duty copper cables wrapped in black, red, or blue insulation (depending on what color your wires were).

Does Electric Golf Cart Solenoid wear out?

An e-starter or an electric golf cart can wear out over time as well and could be an additional component to check if you’re having starter issues or if you need to replace the solenoid.

How to test bad solenoids in Gas Golf Cart?

  • Turn the ignition key to “on”.
  • Wait for solenoid noise (if it starts, then you know your issue is user error)
  • If there’s no noise from the solenoid when turning on the golf cart – that means a bad solenoid.
